Jr., L for Department cf Public Works BACKGROUND OF TH DINNER KEY AUDITORIUM WHEN PONCE bE LEON SA I LED FROM PUERTO RICO I N 1 513 AND Dl S- COVERED FLORIDA, THE SITE OF THE PRESENT AUDI TOR I UM WAS A TINY I SLANb OR "KEY" (FFDti1 SPANISH "CA O" ISLAND) . I T REMAINED SO, WHILE THE PIONEERS OF COCONUT GROVE, THREE CENTUR'I ES LATER, CAME TO THE PALM- SHADED BIT OF LAND FOR PICNIC DINNERS .. HENCE CANE THE OLD NAME "DINNER KEY ". THE UNITED STATES GOVERNMENT FILLED IN THE SHALLOW WATERS AND MADE THE KEY A PART OF THE MAINLAND DURING WORLD WAR T. IT BECAME AN ACTIVE NAVY AIR SASE, TRAINING AVIATORS AND CONDUCTING AN AIR PATROL OF THE STRAITS OF FLORIDA. FOLLOWING WORLD WAR 1, THE BASE WAS USED BY VARIOUS EARLY COD1MERC 1 AL FLYERS, AND BY THE NEW YORK RIO, AND BUENOS AIRES AIRLINE. I N 1930, PAN AMERICAN AIRWAYS TOOK OVER THIS LINE AND MOVED I TS OPERATIONS FROM THE PAN AMERICAN LAND FIELD ON 36TH STREET. PAN AMERICAN BUILT THE PRESENT STEEL BULKHEAD, ADDING 13 ACRES, AND RAISED THE ENTIRE BASE THREE • FEET HIGHER. THE PAN AMERICAN AIRWAYS TERMINAL BUILDING WAS DESTINED TO BECOME THE PRESENT MIAMI AMI I TY HALL. DURI WORLD WAR IT, DINNER KEY AGAIN BECAME A 'MILITARY AREA. THE TWO HANGARS THAT WERE LATER JOINED TO FORM THE DINNER KEY AUDITORIUM WERE BUILT DURING THIS PERIOD ALONG WITH THE BARRACKS BUILDINGS THAT NOW HOUSE SOME or THE CITY or MIAMI omen. THE GOVERNMENT NO Loon HAD USE FOR THIS LAND AT THE END OF THE WAR. IN 10116, THt CITY WAS ABLE TO PURCHASE FOR $1 ALl. Or THIS AREA WITH THE EXCEPTION OF THE U. S. COAST GUARD PROPERTIES WHICH HAS SINCE BEEN ACQUIRED. IN 1048, IN ORDER TO ACCOMMODATE THE AMERICAN LEGION NATIONAL CONVENTION THE CITY JOINED THE TWO HANGAR STRUC- TURES TO FORM ONE LARGE AUDITORIUM FACILITY. IT WAS NECES- SARY TO REMOVE THE COLUMNS ON THE ADJACENT SIDES OF THE TWO HANGARS SO AS TO HAVE A COLUMN-FREE INTERIOR. TWO TRUSSES WERE BUILT IN PLACE TO CARRY THE LOADS OF THE COLUMNS TO BE REMOVED. WHEN THE TRUSSES WERE COMPLETED, THE EXISTING COLUMNS WERE CUT LOOSE, THEREBY TRANSFERRING THEIR LOADS TO THE NEW TRUSSES. ROBERT LAW WEED AND ASSOCIATES WERE CON- SULTANTS ON THIS WORK, AS WELL AS FOR THE WEST SHED AREA AND THE EASTERLY TWO ADDITION WHICH WERE ADDED AT THIS TINT. THE JOINING OF THESE TWO HANGARS RESULTED IN A FACILITY OF APPRCXIMATELY 90 SQUARE FEET AND THEORETICALLY CAPABLE OF ACCOMMODATING A GATHERING OF 10,000 PERSONS. IN 1954, THE ADJOINING RESTAURANT WAS CONSTRUCTED Al A COST OF $131,0OOr PLATES 1, it, AND Ott FOLLOWING SHOW THE EVOLVEMENT OF THE PRESENT DINNER KEY AUDITORIUM, VII s STRUCTURAL STUDY STRUCTURE ROOFING, SIDING, AND WALLS FLOORS REST ROOMS UTILITIES (ELECTRICAL, WATER, SEWERS, DRAINAGE) RESTAURANT AND KITCHEN MISCELLANEOUS S7R M IN GENERAL, THE STRUCTURE IS IN GOOD CONDITION. THE BASIC HANGAR STRUCTURE SHOWS EVIDENCE OF NO MORE THAN SUPERFICIAL RUSTING, AND WITH A MINIMUM OF CARE SHOULD HAVE A USEFUL LIFE OF MANY YEARS. THE STRUCTURAL MEMBERS OF THE ADDITIONS LIKEWISE, IN GENERAL SOUND. SOME EVIDENCE OF LEAKAGE MAY DE NOTED FEW AREAS, NOTABLY THE EAST ADDITION, AND I T I S POSSIBLE THAT SOME STRUCTURAL DECK WILL NEED REPAIR OR REPLACE MENT HERE.

THEY DID RECOMMEND THAT IF WE ANTICIPATED LONG CONTINUED USE OF THE STRUCTURE, A FIELD APPLICATION SHOULD BE MADE OF THEIR STANDARD COLOR COATING. THIS HAS NOT BEEN PURSUED.

THE ORIGINAL HANGAR DOORS ARE STILL I N PLACE, BUT WITH ONE EXCEPTION ARE INOPERATIVE DUE TO THE VARIOUS STRUCTURAL ADDITIONS. THE ONE AT THE NORTHEAST CORNER STILL HAS SEVERAL LEAVES OPERABLE, PERMITTING ENTRANCE OF FLOATS OR OTHER ITEMS. HANGAR DOORS NORTHEAST CORNER FLOORS AS NOTED PREVIOUSLY, THE FLOORS ARE NOT PILE SUPPORTED, SO I T I S NOT SURPRISING TC FIND SOME DIFFERENTIAL SETTLEMENT BETWEEN THE SLAB SECTIONS. THIS I S QUITE NOTICEABLE AT THE NORTH AND SOUTH REST ROOMS AND ADJACENT FACIL EU i ELSE HERE IS NOT SC SEVERE. IMTERICR VIEW (LOOKING SOUTH) REST. ROOMS THE GROUND LEVEL REST ROOMS ARE ALL IN A BADLY DETERIORATED CONDITION. WHILE MUCH OF THIS IS DUE TO GENERAL NEGLECT, THE SERIOUS FLOOR SETTLE- MENT HAS RESULTED IN CRACKED PARTITION WALLS, TOILET PARTITIONS SUSPENDED ABOVE THE FLOORS,.AND PATCHED PLUMBING. BROKEN WATER AND SOIL LINES MAY BE CAUSING INCREASED SETTLEMENT HERE. FLORIDA POWER AND LIGHT PROVIDES 13,000 VOLT PRIMARY SERVICE TO A 500 KVA 208 Y/120 TRANSFORMER LOCATED IN A VAULT INSIDE THE AUDITORIUM. THIS HAS BEEN ADEQUATE POP ALL AUDITORIUM NEEDS TO DATE. ALSO IN THIS VAULT IS A 75 KVA TRANSFORMER SERVING PIERS 4 ANDS OP THE MARINA. THIS HAS NOT BEEN A VERY SATIS- FACTORY LOCATION POR THIS TRANSFORMER, AND I T 1 S HOPED THAT FUTURE DEVELOPMENTS WILL PERMIT ITS RE- LOCATION TO A VAULT OF ITS OWN. THE PRESENT TRANS- FORMER COULD BE LEFT TO PROVIDE A D D I T I O N A L POWER FOR THE AUDITORIUM, OR IT EVEN COULD BE REPLACED WITH ONE AS LARGE AS 167 KVA SHOULD THIS MUCH ADDITIONAL SERVICE BE DESIRED. THE SWITCHGEAR IS INADEQUATE AND OUTDATED AND SHOULD BE REWORKED OR REPLACED. THE AUDITORIUM IS ADEQUATELY SUPPLIED BY WATER AND BY CONNECTIONS TO THE SANITARY SEWER SYSTEM. MOST STORM ATER FLOWS ACROSS THE ADJACENT PAVED AREA TO THE BAY, AND PROPOSED LANDSCAPING IMPROVEMENTS SHOULD TAKE T H I S INTO ACCOUNT. ELECTRIC PA ELS REST.AU NT__AND_! ITCI EN THE KITCHEN IS A WELL DESIGNED, SPACIOUS AND WELL EQUIPPED FACILITY, IT HAS ITS OWN BAKERY AND MEAT STORAGE, AND APPEARS SUITABLE FOR AN EFFICIENT, LARGE VOLUME OPERATION. ONE UNUSUAL FEATURE IS A 10' X 12' REFRIGERATED ROOM FOR STORAGE OF GARBAGE AWAITING PICKUP. IN GENERAL, ONLY MINOR REPAIRS AND CLEANUP WOULD BE REQUIRED TO PUT IT BACK IN SERVICE. HOWEVER, ALL MOTORS AND COMPRESSORS SHOULD PROBABLY BE REWORKED OR REPLACED. THE RESTAURANT AND BAR NEED SOME MINOR REPAIRS. WE WOULD EXPECT ANYONE REOPENING THIS FACILITY WOULD REFURBISH AND REDECORATE THE AREA COMPLETELY. PORTION OF KITCHEN RESTAURANT PORTION OF KITCHEN RESTAURANT MISCELLANEOUS THE LIGHTING HAS NOT BEEN FULLY SATISFACTORY, AND A MORE MODERN AND FLEXIBLE SYSTEM SHOULD BE INSTALLED. THE RESTAURANT, PRINT SHOP (FORMER STORAGE ADDITION), AND SOME OF THE OFFICE SPACES ARE AIR CONDITIONED. THE REMAINDER IS DEPENDENT ON NATURAL VENTILATION - THROUGH LOUVERS ON THE EAST AND WEST SIDES, WITH GRAVITY TYPE VENTILATORS AT THE RIDGES OF THE HANGARS. FIRE PROTECTION WAS PROVIDED AT ONE TIME BY A SPRINKLER SYSTEM. THIS HAS BEEN PARTIALLY DISMANTLED, BUT MOST OF THE SPRINKLER DISTRIBUTION LINES ARE IN PLACE.
